Sudanese war jets launched four missiles into this key South Sudanese state capital Monday, killing at least one and wounding 10 others as tensions continued to rise along the disputed South Sudan-Sudan border.

The jets appeared to be targeting a bridge on the only road linking Bentiu with the conflict zone to the north, where Sudanese and South Sudanese troops last week fought a pitched battle for control of Heglig, an oil town that had long been controlled by Sudan.

A car filled with journalists, including a McClatchy correspondent, had barely crossed the bridge when a missile struck 50 yards away, spouting a dark plume of smoke into the air.
